AI boom accelerates subsea cable demand
The guest argued that the AI boom and the massive data requirements of hyperscalers have accelerated the need for new subsea fiber optic infrastructure, reversing previous industry gluts.
The argument
While some industry observers previously feared a capacity glut, the training and deployment of AI models have dramatically increased global data flow requirements. The guest noted that satellite alternatives lack the capacity to handle this scale, ensuring subsea cables remain the primary backbone of global data transmission.
The thesis, stress-tested
✓ What validates it
- ✓Hyperscalers announcing new multi-billion dollar subsea cable routes
- ✓Increased capital expenditure guidance from major tech firms allocated to global network infrastructure
▸ Risks discussed
- ▸Cyclical economic downturns can freeze expensive cable-laying projects
- ▸Geopolitical tensions can stall or freeze joint international cable projects
Hear it yourself
"Is it basically whether we're talking about the Victorian era cable or now, is it a ship with a giant spool, basically, that slowly unwind as it moves? That's basically. Okay. Yeah. I mean, that hasn't changed. I mean, there's a couple of other things that haven't changed over, but that definitely hasn't changed. They call them a drum or they call it a spool. But, essentially, wind the cable around the spool, and then you load it on board, and then you set off into the high seas. So so that part of it hasn't changed. Of course, the cable is much lighter now, so you can load a lot more cable onto it because it's not sort of thick metal."
